  • Suppression of non-linear effects in low dispersion optical fibers
    Patent number: 9178641
    Abstract: Consistent with the present disclosure, chromatic dispersion is introduced into an optical communication path including multiple segments or spans of dispersion shifted fiber (DSF). The chromatic dispersion generates phase mismatching between optical signals propagating along the optical communication path, i.e., the optical signals are decorrelated, such that mixing products are reduced inmagnitude, and the noise attributable to four wave mixing is correspondingly reduced.
    Type: Grant

    Date of Patent: November 3, 2015
    Assignee: Infinera Corporation
